Acacia brachystachya (bra-chy-stà-chy-a -- pronounced 'brackeeSTAKEeea'), commonly known as umbrella mulga,turpentine mulga or false bowgada, is a shrub in the family Fabaceae. The species occurs in mulga and heath communities on sandhills and rocky ridges in all mainland states of Australia, except Victoria.
Acacia brachystachya grows as a tall, bushy inland shrub to five metres with twisted, spreading stems, and is branched at the base. Like most Acacia species, it has phyllodes rather than true leaves. These may be up to 18 centimetres long, are mostly one to three millimetres wide and a grey-green colour. The flowers are yellow, and held in cylindrical clusters about two centimetres long (up to 25 millimetres). The pods are long and straight, up to 12 centimetres long and 8 millimetres across. It has peduncles up to 10mm with short, stiff hairs.
Acacia brachystachya is a shrub or small tree found in inland Australia. It is found in New South Wales, Northern Territory, Queensland, South Australia, and Western Australia. Within NSW it is usually found in the Central Western Slopes, the Western Plains, and North Far Western Plains.
Acacia brachystachya is commonly found on sandy loam soils near Acacia aneura, and on sandy soils between dunes. In addition to this, in the eastern section of its range, it occurs on shallow stony soils. Its environmental requirements are much alike to those of Acacia ramulosa, albeit with a narrower geographic range. Although A. brachystachya is both related to and confused with A. aneura and A. ramulosa, it is distinguishable in the difference of the pods.
Acacia brachystachya of the fabaceae or mimosaceae families has been categorised as being part of the mimosoideae subfamily. The species name Acacia brachystachya was coined by George Bentham, an English man who never travelled to Australia but wrote Flora Australiensis. Bentham has been referred to as one of the greatest systematic botanists, having contributed considerably to Australian botany.
